ADVANTAGES OF USING

MOBILE MOVING

EQUIPMENTS • They are extremely versatile and flexible

• The equipments can be replaced at short notice

• For a given fleet, the equipment usage can be easily manipulated to meet stocking and reclamation duties.

• Can be used as a sole means of coal handling

• Suitable for building long term stock

DISADVANTAGES OF USING

MOBILE MOVING

EQUIPMENTS • As more operations are required for a given

tonnage this is more labour intensive.

• Higher handling cost

• Higher incidence of serious accidents

• Environmental pollution due to noise and exhaust emissions

• Inherent fire risk

• More maintenance and cost

STACKER RECLAIMER Boben Anto C

ADVANTAGES OF USING

SEMISTATIC EQUIPMENTS

• This enables a very high rate of coal handling to the tune of 700 T/Hr.

• Minimum use of main powers

• It is ideal for use as a stock buffer to regulate different rates of inflow to a lower rate of consumption with minimum man power.

• Effective for homogenization and blending.

• Low operating cost with very large tonnage

• Environmentally more acceptable

• Ideal for short term stocking and reclaiming

• Possesses high availability

• Better safety record

DISADVANTAGES OF USING

SEMISTATIC EQUIPMENTS

• High initial capital cost

• Offers limited storage capacity

• Requires additional plant for long term stocking

• Longer outage during major maintenance

• Rendered out of service in high wind conditions

• High maintenance cost on structures

• Unable to store more coal in a given area

• Coal stock lightly compacted and needs cyclic placing and removal

CONVEYORS

• Layers of cotton or nylon fabric impregnated with rubber

compound with a protective cover of abrasion resistant

rubber.

• The conveyor belt is supported and carried by Idlers or

rollers. • Pulleys are used to drive the belt and impart necessary

tension to it. • The driving unit comprises of a motor coupled to a worm

reduction gear with flexible couplings on the high speed

shaft of the gear box. A fluid coupling is provided between

the reduction gear and driving pulley of the conveyor.

• Maximum inclination 180 Boben Anto C
